C12 and Lynx Hilo USB on Mac stopped talking to each other

Hi, I have a Lynx Hilo with the USB card co0nnected to my Macbook Pro and both have the latest software and firmware updates. However, they no longer communicate using Cubase 12.0.30. The Hilo panel (remote and onboard) shows audio on the correct output pair, but Cubase isn’t receiving it. Both the Hilo and Mac have been power-cycled and everything appearts normal. Except for this! I appreciate any thoughts, thanks.

I power-cycled the rig one more time and, … it is now working. I’m behind on getting some work done or I would try to figure out why it is working now. I’ll get into that once I’m caught up!
